Data-on-Tag: An Approach to Privacy friendly Usage of RFID Technologies

The proliferation of RFID technology in many application areas has caused serious concerns regarding threats to consumer privacy. To a large extent, this is due to the widespread approach of storing RFID-based data via a global network (Data-on- Network), enabling its linkage and analysis. Based on a description of existing privacy threats and a presentation of the two general storage approaches, we argue that privacy concerns can be narrowed down by exclusively storing data on RFID tags (Data-on-Tag). We support this assumption by presenting advantages for consumers as well as for companies and describe some novel application areas emerging from tag-centric approaches
